Summary For Reaction Orders 0, 1, 2, and n
Elementary reaction steps with order 3 (called ternary reactions) are rare and unlikely to occur. However, overall reactions composed of several elementary steps can, of course, be of any (including non-integer) order.

Where M stands for concentration in molarity (mol · L−1), t for time, and k for the reaction rate constant. The half-life of a first-order reaction is often expressed as t1/2 = 0.693/k (as ln2 = 0.693).

Famous quotes containing the words summary, reaction and/or orders:
“Product of a myriad various minds and contending tongues, compact of obscure and minute association, a language has its own abundant and often recondite laws, in the habitual and summary recognition of which scholarship consists.”
—Walter Pater (1839–1894)
“Sole and self-commanded works,
Fears not undermining days,
Grows by decays,
And, by the famous might that lurks
In reaction and recoil,
Makes flames to freeze, and ice to boil.”
—Ralph Waldo Emerson (1803–1882)
“Your money’s no good here. Orders of the house.”
—Stanley Kubrick (b. 1928)
